Abstract
An opening pivot mechanism for a window or any type of closure that permits the closure to be opened in three directions from a single operator that includes three actuator rods with integral cylindrical bosses that define two pivot pins on each of three axes for slotted hinges carried by the closure. The actuator rods are simultaneously reciprocated by the operator through a series of links to position one of the rods with its pivot pins in their associated hinges thus defining the selected pivot axis, and to position at the same time reduced portions on the other two actuator rods in the remaining hinges so these rods can pass through the slots in their hinges during opening movement of the closure.
Claims11
In a hinge and locking mechanism for a generally rectangular closure member that may be opened by pivotal movement about at least two axes, a stationary generally rectangular frame member surrounding and supporting the closure member, hinge means on each of the axes mounted on one of the members, the improvement comprising;
- two spaced hinges on each of said axes on one of said members, two spaced pivot pins on each of the axes mounted on the other of said members selectively positionable in each of the hinges to define pivot axes for the closure member when the pins are in the hinges, and a common operator for all of the pins, said pivot pins on each axis being formed integrally and coaxially with an actuator rod connected to the common operator, said pivot pins being shiftable axially to a position freeing the hinges from the pivot pins without shifting the closure member laterally in the plane of the closure member.
In a hinge and locking mechanism for a generally rectangular closure member in a generally rectangular frame member that is openable about at least three axes each located generally along and parallel to one of the sides of the rectangular closure member, hinge means mounted on one of the members on each of said axes, first, second and third pin means mounted on the other of said members along each of said axes and selectively movable into and out of the hinge means, the improvement comprising;
- a common operator for the first, second and third pin means and mounted on the other of said members movable to a first position engaging the first pin means into one of the hinge means and disengaging the second and third pin means from other of said hinge means to permit pivotal movement of the closure member about a first of said axes, said common operator being movable to a second position engaging the second pin means into one of the other hinge means and disengaging the first and third pin means from the remaining hinge means to permit pivotal movement of the closure member about a second of said axes, and said common operator being movable to a third position engaging the third pin means in the other of said other hinge means and disengaging the first and second pin means from the remaining hinge means to permit pivotal movement of the closure member about the third of said axes.
In a hinge and locking mechanism for a generally rectangular closure member that may be opened by pivotal movement about at least two axes, a stationary generally rectangular frame member surrounding and supporting the closure member, hinge means on each of the axes mounted on one of the members, pin means carried by the other of said members along each of said axes being selectively positionable in the hinge means, and operator means for selectively moving the pin means to permit opening of the closure member about either axes, the improvement comprising;
- each of said hinge means on each axis including two spaced hinges each having a cylindrical portion with a side slot therein extending longitudinally therethrough, and an actuator rod on each of said axes driven by the operator means extending through the cylindrical portion of each of the hinges, each of said actuator rods having spaced cylindrical bosses and reduced portions adjacent the cylindrical bosses having a width less than the width of the slot in the cylindrical portion of the hinges so that when one of the actuator rods is positioned with said reduced portions in the cylindrical portions the reduced portions may pass through the slots to permit closure member opening without laterally shifting the closure member in the plane of the closure member.
In a hinge and locking mechanism for a generally rectangular closure member that may be opened by pivotal movement about at least two axes, a stationary generally rectangular frame member surrounding and supporting the closure member, hinge means on each of the axes mounted on one of the members, pin means carried by the other of said members along each of said axes being selectively positionable in the hinge means, and operator means for selectively engaging the pin means to permit opening of the closure member about either axes, the improvement comprising;
- means directly engageable with the pin means and separate from the operator member and being responsive to opening movement of the closure member about one of said axes for automatically and positively locking the pin means on said one axis from all axial movement while permitting relative rotational movement between the pin means and the hinge means on said one axis.
